How to remove perfectly overlapping curves?

Rhino
1

I created a simple pattern by rotating an regular polygon around z-axis.
In the result there are lines overlaping so I like to delete them, and make lines in the pattern joined.

What I tried:
I exploded the result pattern and tried re-join them, but the result is not ideal.
I used SelDup command after exploding, but the result is not the ones overlappings, but still all the curves.

Thanks!

_SelDup to select duplicate objects after you’ve exploded the curves.

建议看一下seldup以及各种sel命令的帮助。
我重新看了一下你的操作，并复现了一下。
假设你已经框选了所有曲线，而这个曲线中已经包含重复物体，再次运行seldup时，他将会在你“未选中”的物体范围内寻找，你已经选中的曲线，rhino不会做任何判断和选取操作。所以命令栏提示内的2个重复曲线来自于你画面之外。

重新用正确的方式运行seldup即可得到你想要的结果。

谢谢！空白处用seldup确实找到了重叠线，而且刚才想起来分叉的曲线是不能join在一起，因为曲线有方向。

是的，join只能一对一，不能三岔口之类的。
